Why they don't wear their wedding bands?

This is just an observation; I don’t know why other married people haven’t worn their wedding bands after the following months or years of their nuptial. I wasn’t able to wear this kind of ring but if I have the chance for sure I will forever wear it. Ring signifies love and commitment to each other so it should not be forgotten. Sadness, because as I said I’ve seen married couple especially mens wedding bands are being neglected. Some of them just wanted to hide it in their jewelry box. Aside from that some of wedding rings are put in pawn shops. Well, this is just my observation and if I’m wrong you can correct me =).
